Grinding Is Grinding Wheel On A Grinder As A Method Of Cutting Tools For Machining Of The Workpiece

Zibo King Abrasives Co.,Ltd | Updated: Jan 21, 2017

Grinding is grinding wheel on a grinder as a method of cutting tools for machining of the workpiece. The characteristic of this method is:

(1) Due to the grinding wheel abrasive itself has a very high hardness and heat resistance, grinding machining high hardness materials, such as hardened steel, carbide, etc.

(2) Grinding wheels and grinding characteristics of grinding technology of micro cutting system can even, AP=0.001~0.005mm; grinding speed is very high, up tov=30~50m/s General; grinding stiffness using hydraulic transmission, so that grinding can economically achieve high Machining accuracy (it6~IT5) and small surface roughness (RA=0.8~0.2 μ m). One of the main methods of grinding is a finishing ofparts.

(3) Due to the dramatic friction, grinding temperature is very high. This can cause stress and deformation of the workpiece, even resulting in burns on the surface of the workpiece. Must be poured so grinding coolant, to lower the temperature. Coolant can also chip and lubrication.

(4) The radial force when grinding is very large. The flexibility of the machine tool-grinding wheel-workpiece system caused yield and the actual cutting depth is less than the nominal depth of cut. So when grinding will be completed should not feedmill in order to eliminate errors.

(5) After the abrasive wear, grinding force increases, resulting in grinding grain broken or falls off, brought back sharp edge, this attribute is called "self-sharpening". Self-sharpening grinding in a certain period to work properly, but after a certain time should be manually trimmed to avoid increased grinding forces cause vibration, noise and damage the workpiece surface quality.
